“It speaks to the maturity of those young guys that have come in,” 49ers LB Fred Warner said via Sports Illustrated’s Albert Breer. “It’s all about the preparation they’ve put in to be ready for their moment, because they knew from OTAs that they were gonna have a chance to come in and be guys for us right away. My hats to them for being prepared for that moment. They’re only going to continue to get better.”

The 49ers have been without some key players like QB Brock Purdy, TE George Kittle and WR Brandon Aiyuk due to injuries, and while they’ll get all three of those guys back at some point, they just lost DE Nick Bosa for the year to a torn ACL. Warner thinks the team can push past that and continue to improve, though.

Cardinals

Cardinals WR Marvin Harrison Jr. hasn’t quite lived up to his standards coming out of the draft, and he had some tough moments in their Week 3 loss against the 49ers. Harrison admitted he needs to play at a higher level because his performance is hurting the team. 

“Everybody’s got a job to do and I’m not doing it at a high enough level at the moment,” Harrison said, via Tyler Drake of ArizonaSports.com. “I think I know what I’m capable of and to go out there and not play to nowhere near my abilities is frustrating. It hurts the team and I need to get better.”
